BOOK-REST.

To'all whom it may concern:

Be it known that I, FREDERICK A.

'SCHLANGER, a citizen of the United States,

and resident of Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Book-Rests, of which the following is a specification.

This invention relates to book rests and more especially to pivoted supports adapted to be secured below the seat of a chair and swing out of use to one side or be thrown around in front of the chair so the support or platform may be used and at the same time support the arm of the occupant of the chair or be'thrown to the front for reading or writing in that position. The support may also be used for other purpose than a book rest and consists ofdetails, all of which will be more fully described in the following specification, set forth in the appended claim and illustrated in the accompanying drawings, wherein:

Figure 1, is a plan view of a chair showin the support and rest atone side.

Fig. 2, is .a side elevation of the chair with the support and rest swung .around to the front.

Fig. 3, is a side view ofthe book rest.

' Fig.4,is a side view of the support pivot.

Fig. 5,'shows how the support may carry a telephone or other article.

Fig. 6, is a side view of a chair with a modified form of book rest.

Fig. 7 is another modifiedform of book rest.

Fig. 8, shows the side rack for the book rest.

Fig. 9, is a sectional view of the same. Fig. 10, is a modified form of pivot hub.

Fig. 11, is a view of the under side of the v pivot of the book rest.

The object of the invention is to provide a simple support adapted to be pivoted beneath the seat of the chair and it consists of a substantially U-shaped bracket comprising the upright 10 and two horizontal arms 11 and 12, the latter having at its end a hub 13 and to which it is secured by means of the socket 14. The hub 13 is adapted to fit about a pin 15 or, as'shown in Fig. '5, it may be carried by the screw 16 of an ordinary oflice chair. To prevent too free movement of the bracket, the hub may be provided with a tooth 17 to fit in the indentations 18in the washer 19 to hold it at any Specification of Letters Patent.

Application filed December 28, 1915. Serial No. 69,012.

desired point to which it is swung, but a spring 20 as shown in Fig. 6 or friction 'washers 21, as in Fig. 10, may be used for the same purpose. The arm 11 of the bracket isnot of the same radial angle from the'upright as the arm 12 but may depart to any degree that is found desirable, although the two arms are on parallel planes.

The play of the arm 12 is always between the two side legs of the chair and the angle of the arm 11 is therefore arranged to be practically parallel with the side of the chair or its front, according to the use to which the rest is being put. The movement of the arm 12 is limited by the set screws 22and 23 so that it will not strike and jar either of the side legs of the chair. The entire bracket and book rest may be made and adapted to be attached to the seat of the chair by means of the frame or spider 24, except in the instance shown in Fig. 5.

Various forms of tables, rests and platforms maybe such as shown in the several views but a preferable book rest is shown in Figs. 1, 2 and 3 and consists of the base 25 carrying on its under side the plate 26 with the pivot 27 at one end and a stop stud 28 at the other. This pivot 27 permits the base 25 to be swung around the head 29 of the arm 11 so that it may occupy the position shown in Fig. 1 or thrown across the front of the seat when the bracket is swung outward, the stop 28 arresting it'in either direction.

To the base 25 is hinged a movable member 30 and adapted to be held at any desired angle by brace rods 31 at each side and whose lateral ends engage the notches 32, in a plate 33 secured to each side of the base. 7 This plate 33 is best shown in Fig. 8, and the end of each rod 31 rests in a slot 34 when the member 30 is not elevated but as it is raised, the rod travels down the slot 34 and may drop into a notch when the desired inclination is reached. When returning to its starting point the rod may move through the slot 35 and through a gate 36 to its lodging place.

As shown in Fig. 6, the book rest may consist of a single piece 36 and may be swiveled to the arm 11 at 37 so that it may be turned on a pivot 38 and elevated to the desired angle as shown in dotted lines, while in Fig. 7 a single elevating rod 39 is employed and the movable member may be held at the desired angle by the notches 40.

7 from the essential features above described.

What I claim as new is In a book rest, the combination of a substantially U-shaped frame comprising two t,- horizontal and a vertical rod a pivot securing the end of one horizontal member to the underside of the bottom of a chair .seat, means at the pivot for permitting the swingof the pivoted member within predetermined limits, and a rest carried at the 15 end of the other horizontal member and adapted to maintain a tangential relatlon with the seat of the chair as the frame is swung on the pivot.

Signed at New York, in the county of 20' New York andState of New York, this 23d day of December, A. D. 1915.
